Britney Spears' latest gym selfies will make you do a double take: See the photos!

Britney Spears' ripped abs have been the public eye since her '...Baby One More Time Days', but her latest gym selfies have totally raised the bar.

On April 30, the 35-year-old mum-of-two shared a snap of her impossibly toned figure to Instagram. The pop singer wore a hot pink sports bra and gray track shorts folded down at the waistband to give a better look at her chiseled tummy.

In a second photo, Britney showed off how years of dancing can make you really, um, really flexible as did a full split, putting her sculpted legs and thighs on display.
"Back at the gym.... stretch and run all the way," she captioned the pics.

Britney and her itty-bitty yellow bikini recently made a splash on the social media site when she shared a video of herself doing stunts in the pool with 23-year-old boyfriend Sam Asghari.

She previously opened up about how things first heated up with fitness model Sam, whom she met while filming her 'Slumber Party' music video last year.

"We were doing the scene where I was doing the walk scene through the hall to go through the door to go to the bedroom, and we were sitting there and waiting and waiting together for like 20 minutes at a time."

"We were having to be literally stuck there together, so we were basically forced to talk to each other," she continued.

"We started talking about sushi and started talking about things we like and like we should go to sushi one day."

Sam gave Britney his number, but the singer admitted she waited five months to call him!

"It was one of those things that we were having a conversation to get through the experience, you know? I kept his number, and it was so weird — it was like five months later, and I found his number in my bag. I was like, 'He is really cute. This guy is really cute.' So then I called him, and ever since then, he is just a really fun, funny person."
